be used for safe control of towed
vehicles and for trailers where the
Gross Combined Weight of the
towing vehicle plus the trailer
exceed the Gross Vehicle Weight
Rating of the towing vehicle.
The gross combined weight must
never exceed the Gross Combined
Weight Rating.
Note:
For trailer towing
information refer to the RV and
Trailer Towing Guide available at
an authorized dealer. WARNING: Do not exceed
the GVWR or the GAWR
specified on the certification
label. WARNING:
Do not use
replacement tires with lower
load carrying capacities than the
original tires because they may
lower your vehicle's GVWR and
GAWR limitations. Replacement
tires with a higher limit than the
original tires do not increase the
GVWR and GAWR limitations. WARNING: Exceeding any
vehicle weight rating can
adversely affect the
performance and handling of
your vehicle, cause vehicle
damage and can result in the
loss of control of your vehicle,
serious personal injury or death. Steps for determining the
correct load limit:
1. Locate the statement "The
combined weight of occupants
and cargo should never exceed
XXX kg or XXX lb." on your
vehicle ’s placard.
2. Determine the combined
weight of the driver and
passengers that will be riding
in your vehicle.
3. Subtract the combined weight
of the driver and passengers
from XXX kg or XXX lb.
4. The resulting figure equals the
available amount of cargo and
luggage load capacity. For
example, if the “XXX” amount
equals 1,400 lb. and there will
be five 150 lb. passengers in
your vehicle, the amount of
available cargo and luggage
load capacity is 650 lb.
(1400-750 (5 x 150) = 650 lb.)
5. Determine the combined
weight of luggage and cargo
being loaded on the vehicle.
That weight may not safely
exceed the available cargo and
luggage load capacity
calculated in Step 4.
6. If your vehicle will be towing a
trailer, load from your trailer
will be transferred to your
vehicle. Consult this manual to
determine how this reduces the
available cargo and luggage
load capacity of your vehicle.

TOWING A TRAILER
WARNING: Towing trailers
beyond the maximum
recommended gross trailer
weight exceeds the limit of your
vehicle and could result in engine
damage, transmission damage,
structural damage, loss of
vehicle control, vehicle rollover
and personal injury. WARNING:
Do not exceed
the GVWR or the GAWR
specified on the certification
label.
Note: See
Recommended
Towing Weights (page 289).
Your vehicle may have electrical
items, such as fuses or relays,
related to towing. See
Fuses
(page 312).
Your vehicle's load capacity
designation is by weight, not by
volume, so you cannot necessarily
use all available space when
loading a vehicle or trailer.
Towing a trailer places an extra
load on your vehicle's engine,
transmission, axle, brakes, tires
and suspension. Inspect these
components periodically during,
and after, any towing operation. Load Placement
To help minimize how trailer
movement affects your vehicle
when driving:
•
Load the heaviest items closest
to the trailer floor.
• Load the heaviest items
centered between the left and
right side trailer tires.
• Load the heaviest items above
the trailer axles or just slightly
forward toward the trailer
tongue. Do not allow the final
trailer tongue weight to go
above or below 10-15% of the
loaded trailer weight.
• Select a ball mount with the
correct rise or drop and load
capacity. When both the
loaded vehicle and trailer are
connected, the trailer frame
should be level, or slightly
angled down toward your
vehicle, when viewed from the
side.
When driving with a trailer or
payload, a slight takeoff vibration
or shudder may be present due to
the increased payload weight.
Additional information regarding
proper trailer loading and setting
your vehicle up for towing is
located in another chapter of this
manual. See
Load Limit (page
282).
You can also find information in
the
RV & Trailer Towing Guide
available at your authorized
dealer, or online.

Before Towing a Trailer
Practice turning, stopping and backing up
to get the feel of your vehicle-trailer
combination before starting on a trip.
When turning, make wider turns so the
trailer wheels clear curbs and other
obstacles.
When Towing a Trailer
•
Do not drive faster than 70 mph
(113 km/h) during the first 500 mi
(800 km).
• Do not make full-throttle starts.
• Check your hitch, electrical connections
and trailer wheel lug nuts thoroughly
after you have traveled 50 mi (80 km).
• When stopped in congested or heavy
traffic during hot weather, place the
gearshift in park (P) to aid engine and
transmission cooling and to help A/C
performance.
• Turn off the speed control with heavy
loads or in hilly terrain. The speed
control may turn off automatically
when you are towing on long, steep
grades.
• Shift to a lower gear when driving down
a long or steep hill. Do not apply the
brakes continuously, as they may
overheat and become less effective.
• If your transmission is equipped with a
Grade Assist or Tow/Haul feature, use
this feature when towing. This provides
engine braking and helps eliminate
excessive transmission shifting for
optimum fuel economy and
transmission cooling.
• Allow more distance for stopping with
a trailer attached. Anticipate stops and
brake gradually.
• Avoid parking on a grade. However, if
you must park on a grade:
1. Turn the steering wheel to point your vehicle tires away from traffic flow. 2. Set your vehicle parking brake.
3. Place the automatic transmission in
park (P).
4. Place wheel chocks in front and back of the trailer wheels. (Chocks not
included with vehicle.)
Launching or Retrieving a Boat or
Personal Watercraft (PWC)
Note: Disconnect the wiring to the trailer
before backing the trailer into the water.
Note: Reconnect the wiring to the trailer
after
removing the trailer from the water.
When backing down a ramp during boat
launching or retrieval:
• Do not allow the static water level to
rise above the bottom edge of the rear
bumper.
• Do not allow waves to break higher
than
6 in (15 cm) above the bottom
edge of the rear bumper.
Exceeding these limits may allow water to
enter vehicle components:
• Causing internal damage to the
components.
• Affecting driveability, emissions, and
reliability.
Replace the rear axle lubricant anytime
the rear axle has been submerged in water.
Water may have contaminated the rear
axle lubricant, which is not normally
checked or changed unless a leak is
suspected or other axle repair is required.

REDUCED ENGINE
PERFORMANCE
WARNING: If you continue to drive
your vehicle when the engine is
overheating, the engine could stop
without warning. Failure to follow this
instruction could result in the loss of
control of your vehicle.
If the engine coolant temperature gauge
needle moves to the upper limit position,
the engine is overheating. See Gauges
(page 106).
You must only drive your vehicle for a short
distance if the engine overheats. The
distance you can travel depends on
ambient temperature, vehicle load and
terrain. The engine continues to operate
with limited power for a short period of
time.
If the engine temperature continues to rise,
the fuel supply to the engine reduces. The
air conditioning switches off and the engine
cooling fan operates continually.
1. Gradually reduce your speed and stop your vehicle as soon as it is safe to do
so.
2. Immediately switch the engine off to prevent severe engine damage.
3. Wait for the engine to cool down.
4. Check the coolant level. See
Engine
Coolant Check (page 331).
5. Have your vehicle checked as soon as possible.
ECONOMICAL DRIVING
Fuel economy is affected by several things
such as how you drive, the conditions you
drive under and how you maintain your
vehicle. You may improve your fuel economy by
keeping these things in mind:
•
Accelerate and slow down in a smooth,
moderate fashion.
• Drive at steady speeds.
• Anticipate stops; slowing down may
eliminate the need to stop.
• Combine errands and minimize
stop-and-go driving.
• Close the windows for high-speed
driving.
• Drive at reasonable speeds (traveling
at
55 mph (88 km/h) uses 15% less
fuel than traveling at 65 mph
(105 km/h)).
• Keep the tires properly inflated and use
only the recommended size.
• Use the recommended engine oil.
• Perform all regularly scheduled
maintenance.
Avoid these actions; they reduce your fuel
economy:
• Sudden accelerations or hard
accelerations.
• Revving the engine before switching it
off.
• Idle for periods longer than one minute.
• Warm up your vehicle on cold
mornings.
• Use the air conditioner or front
defroster.
• Use the speed control in hilly terrain.
• Rest your foot on the brake pedal while
driving.
• Drive a heavily loaded vehicle or tow a
trailer.

Tires
•
Maintain recommended air pressure.
Miscellaneous
• Make sure all linkages, cables, levers
and pins under your vehicle are covered
with grease to prevent rust.
• Move vehicles at least 25 ft (7.5 m)
every 15 days to lubricate working parts
and prevent corrosion.
Removing Vehicle From Storage
When your vehicle is ready to come out of
storage, do the following:
• Wash your vehicle to remove any dirt
or grease film build-up on window
surfaces.
• Check windshield wipers for any
deterioration.
• Check under the hood for any foreign
material that may have collected
during storage such as mice or squirrel
nests.
• Check the exhaust for any foreign
material that may have collected
during storage.
• Check tire pressures and set tire
inflation per the Tire Label.
• Check brake pedal operation. Drive
your vehicle
15 ft (4.5 m) back and
forth to remove rust build-up.
• Check fluid levels (including coolant,
oil and gas) to make sure there are no
leaks, and fluids are at recommended
levels.
• If you remove the battery, clean the
battery cable ends and check for
damage.
Contact an authorized dealer if you have
any concerns or issues. BODY STYLING KITS
(IF EQUIPPED)
The distance between the underside of
your vehicle and the ground is less than
that of other models. Drive with extreme
care to avoid damage to your vehicle.

Explorer (CTW), enUSA, Edition date: 202007, Second-Printing Vehicle Care

GENERAL INFORMATION
The recommended tire inflation pressures
are found on the Tire Label which is
located on the B-pillar or the edge of the
driver door. This information can also be
found on the Safety Compliance
Certification Label, affixed to either the
door hinge pillar, door-latch post, or the
door edge that meets the door-latch post,
next to the driver
’s seating position.
We strongly recommend maintaining these
tire pressures at all times. Failure to follow
the tire pressure recommendations can
cause uneven treadwear patterns, reduced
fuel economy, and adversely affect the
way your vehicle handles.
Note: Check and set the tire pressure at the
ambient temperature in which you are
intending to drive your vehicle and when the
tires are cold.
Note: Check your tire pressures at least
once per month.
If your vehicle has a spare tire, set the
pressure to the highest value given for your
vehicle and tire size combination.
Use only approved wheels and tire sizes;
using other sizes could damage your
vehicle.
If you change the diameter of the factory
installed tires, the speedometer could
display the incorrect speed. This could
effect the functionality of the 4WD system
(if equipped). Take your vehicle to an
authorized dealer and have the engine
management system reprogrammed.
If you intend to change the size of the
factory installed tires, check the suitability
with an authorized dealer.
Additional information related to the
functionality and maintenance of your tires
can be found in the Wheels and Tire
section. See Tire Care (page 353). Self-Sealing Tires
(If Equipped)
Self-Sealing tires are a special type of tire
that have a material on the inside of the
tire that can seal punctures up to
0.2 in
(6 mm) in diameter in the tread area. This
material does not protect from damage or
punctures in the sidewall of the tire.
Self-sealing tires can be identified by the
tire manufacturer with a special mark.
If your TPMS warning light comes on,
inspect your tires for damage and re-inflate
your tires to the pressure indicated on the
tire placard. See
Tire Pressure
Monitoring System (page 368). If your
tires are damaged or continue to lose air,
take your vehicle to the nearest authorized
dealer to have your tires inspected and
repaired/replaced as necessary.
Note: Replace self-sealing tires with
self-sealing tires to maintain the
functionality provided.
Note: Do not drive on a deflated
self-sealing tire. This damages the tire
beyond repair.
Notice to utility vehicle and truck
owners WARNING:
Vehicles with a higher
center of gravity (utility and four-wheel
drive vehicles) handle differently than
vehicles with a lower center of gravity
(passenger cars). Avoid sharp turns,
excessive speed and abrupt steering in
these vehicles. Failure to drive cautiously
increases the risk of losing control of your
vehicle, vehicle rollover, personal injury
and death. WARNING:
In a rollover crash, an
unbelted person is significantly more
likely to die than a person wearing a
seatbelt.
